Many residents have already voiced concerns about the diversion route on Peaslands Road and Mount Pleasant Road, where street parking effectively turns the roads into a single lane.

Colin G, commenting on the community social media network Streetlife, said: “I used South Road and Mount Pleasant Road late morning to avoid the long queue at Memorial and it was virtually single lane and queuing all the way to the lights. It will be hell when the school goes back.”

Daniel V, also speaking on Streetlife, said: “Perhaps it would have been an idea to suspend parking on Peaslands Road and Mount Pleasant Road during the diversion. The extra traffic on a road that is effectively single lane at points probably will not be good.”
